What the Ryzen 7 PRO 7745 is
The Ryzen 7 PRO 7745 is an 8-core and 16-thread desktop processor that AMD launched on June 13, 2023 for business desktops. Eight Zen 4 cores with simultaneous multithreading run at 3.8 GHz base and up to 5.3 GHz boost, plus 8 MB of L2 and 32 MB of L3. The chiplet design uses TSMC 5 nm compute with a 6 nm I/O die. Default TDP is 65 W with PRO security for fleets.
Radeon Graphics with 2 compute units at up to 2200 MHz cover office displays without a discrete card. DDR5-5200 in two channels up to 128 GB with ECC on capable boards feeds 8 cores. PCIe 5.0 x28 with 24 usable lanes serves NVMe and discrete GPUs where needed.
Business creation desks fit here. Eight cores keep office suites plus security agents smooth at 65 W. Buyers who need 12 cores for heavier builds should take the AMD Ryzen 9 PRO 7945 with 64 MB cache instead, since this 7745 prioritizes balanced power.
Socket and motherboard compatibility
The PRO 7745 fits AM5 on 600 and 800 series boards with Raphael support. A620, B650, B650E, X670, X670E plus B840, B850, X870 and X870E list the SKU. The LGA1718 package uses standard AM5 coolers.
Memory is DDR5-5200 in two channels up to 128 GB with ECC on capable boards. PRO fleets favor ECC coverage. No EXPO overclocking on PRO parts.
Business shoppers compare PRO 7000 on cores. The 7745 trails 12-core twins on parallel loads. The Socket vs chipset: what decides whether a CPU works guide covers AM5 BIOS updates.
Memory, PCIe and cooling
DDR5-5200 in dual channels up to 128 GB is the PRO standard. Creation work benefits from 32 GB where VMs stay open. Dual modules are preferred.
PCIe 5.0 x28 with 24 usable lanes serves GPU plus NVMe. PRO builds pair integrated graphics with one fast SSD.
Cooling is 65 W boxed class. Towers cut noise. Airflow decides repeat 5.3 GHz behavior.
Upgrade paths
The AM5 socket allows moves to 12-core PRO on the same board. Memory and NVMe can also grow. BIOS must list the target.
A working PRO 7745 lasts office years. Granite Ridge needs only a BIOS update where listed.
